Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lock device that can change the setting of a special key that can be unlocked as appropriate.

[Prior Art] Conventionally, an inner cylinder is rotatably housed in an outer cylinder, and a lock pin storage hole and a lock pin insertion hole are formed across the outer cylinder and the inner cylinder and extend into the key insertion hole in the inner cylinder. A plurality of lock pins are provided in line in the direction of the core line, and the lock pins are stored in the lock pin storage hole and the lock pin insertion hole, respectively, with a force applied to move the lock pin in the direction of the key insertion hole in the inner cylinder. , Only when a special key having a specific key thread is inserted into the key insertion case, the relationship between the plurality of grooves of the key thread and the length of the dividing element of the lock pin causes the inner peripheral surface of the outer cylinder to The divided portions of the lock pin dividing elements for each of the lock pin storage hole and the lock pin insertion hole align with the boundary portion with the outer peripheral surface of the inner cylinder, so that the locked state of the inner cylinder with respect to the outer cylinder is released. A locking device is known.

[Problems to be Solved by the Invention] However, in the above conventional lock device, the dividing elements of the lock pin cannot be rearranged.

Therefore, if one of the special keys unique to a locking device is lost or stolen, the locking device itself must be replaced to avoid misuse of the special key, and the locking device may be wasted. There were problems such as the time it took to replace the lock device.

In particular, if the same lock device is used in many pachinko machines installed in a pachinko game parlor, if only one key is lost or stolen, the lock device will be locked. In many cases, the entire locking device had to be replaced, resulting in a large economic loss.

In addition, in conventional locking devices, in order to prevent unauthorized use of duplicate keys, many types of locking devices must be manufactured, which is troublesome for locking device manufacturers.

This invention was made to eliminate these inconveniences, and even if the special key unique to the lock device is lost or stolen, the special key for unlocking the lock can be freely changed without replacing the lock device itself. The purpose of the present invention is to provide a locking device that obtains the desired results.

[Means for Solving the Problems] In order to solve the above problems, a lock device according to the present invention has an inner cylinder rotatably housed in an outer cylinder, and a key difference in the inner cylinder across the outer cylinder and the inner cylinder. A plurality of lock pin storage holes and lock pin insertion holes are provided in the direction of the core line, and the lock pins are inserted into the lock pin storage holes and the lock pin insertion holes, respectively, in the direction of the key insertion hole in the inner cylinder. Only when a special key having a specific key thread is inserted into the key insertion hole when the special key is stored in a state where it is given a moving force, the plurality of grooves of the key thread and the length of the dividing element of the lock pin are inserted. In relation to this, the divided portions of the lock pin dividing elements for each of the lock pin storage hole and the lock pin insertion hole coincide with the boundary between the inner peripheral surface of the outer cylinder and the outer peripheral surface of the inner cylinder, so that the outer cylinder is A recombination in which the lock pin insertion hole of the inner cylinder can communicate with an inner peripheral position shifted in phase from the lock pin storage hole of the outer cylinder of a locking device in which the locked state of the inner cylinder with respect to the cylinder is released. A recombinant lock pin storage hole is provided, and a recombinant dividing element of the lock pin is recombinably stored in the recombinant lock pin storage hole.

[Function] When you want to change the special key for unlocking, insert the currently set special key into the key insertion hole of the lock device and rotate the inner cylinder, so that the lock pin insertion hole of the inner cylinder can be changed. Align it with the position of the recombination lock pin storage hole in the outer cylinder, then pull out the special key, then insert another special key with a different key thread into the key insertion hole, and insert it into the inner cylinder. By aligning the lock pin insertion hole with the lock pin storage hole of the outer cylinder and pulling out the special key, the special key for unlocking can be freely changed.
